feat(DEP0064): handle tls.createSecurePair deprecation

[technologic-technologic]

This pull request implements the codemod to replace deprecated tls.createSecurePair() with TLSSocket, addressing DEP0064.

• This PR closes feat: handle tls.createSecurePair() depreciation #127

Changes included:

• Updated the codemod workflow to transform createSecurePair(...) into new TLSSocket(underlyingSocket, {...}), preserving tls.TLSSocket for namespace usage.
• Rewrote imports to replace { createSecurePair } with { TLSSocket } in CJS/ESM (keeps namespace imports intact).
• Renamed assigned variables pair → socket where applicable.
• Added tests for cjs/esm (destructured, namespace, flags, and mixed symbols).
• Ensured idempotent runs and minimal, repo-style edits.
• Added README.md and package.json metadata.
• Added tests for assigned variables, destructured imports.

This PR is part of the feature branch feat/tls-createSecurePair-to-TLSSocket.
